SPIDER Automation | All-Metal Compact UGV Suspension (B) | 3kg Per-Wheel Load Capacity for DDSM210 & DDSM400
Product Overview
The All-Metal Compact UGV Suspension (B) is a compact spring-based suspension assembly developed for unmanned ground vehicle (UGV) and autonomous ground vehicle (AGV) chassis using compatible DDSM210 and DDSM400 hub motors. Its all-metal construction and high-strength spring provide a specified load capacity of 3kg per wheel.
The compact mechanical arrangement helps simplify hub-motor integration while reducing the space required for suspension mounting within the chassis. It is designed for installation on compatible 20-series aluminium profiles and includes European-standard T-nuts for mounting.
Open-source chassis models are available for both profile-based and fully enclosed chassis designs. These models support secondary development, allowing engineers and makers to modify the chassis layout and adapt it for 3D printing or sheet-metal fabrication.
Technical Features & Functional Characteristics
- All-Metal Suspension Assembly: Uses an all-metal construction for mechanical integration into compact mobile robot chassis.
- High-Strength Spring: Provides the specified 3kg per-wheel load capacity for Suspension B.
- Compact Mechanical Layout: Helps minimise the space occupied by the wheel suspension arrangement, supporting more efficient chassis packaging.
- Hub Motor Integration: Designed for compatible DDSM210 and DDSM400 hub motor configurations.
- 20-Series Aluminium Profile Mounting: Includes European-standard T-nuts for attachment to compatible 20-series aluminium extrusion profiles.
- UGV & AGV Chassis Integration: Provides a suspension mounting option for compact unmanned and autonomous ground vehicle platforms.
- Open-Source Chassis Models: Profile chassis and fully enclosed chassis models are available to support design modification and secondary development.
- Flexible Manufacturing Options: The available chassis models can be adapted for fabrication using 3D printing or sheet-metal processes.
- Wiring Layout Considerations: The suspension slot can be considered during chassis design to help plan body cut-outs and cable routing.
Suspension Design & Hub Motor Compatibility
The Suspension (B) assembly is intended for compact mobile robot platforms that use compatible DDSM210 or DDSM400 hub motors. Its spring-based arrangement provides a mechanical suspension interface between the wheel assembly and the vehicle chassis.
The specified load capacity is 3kg per wheel. For a multi-wheel vehicle, the total supported vehicle load must be considered alongside the number of suspension units, load distribution, centre of gravity, dynamic forces and the mechanical limits of the complete chassis.
The compact layout can help reduce the space needed for suspension integration, making it useful when designing small robotic platforms with limited chassis volume.
Aluminium Profile Mounting & Chassis Development
The suspension includes 20-series European-standard T-nuts for mounting on compatible aluminium extrusion profiles. This provides a practical mounting approach for modular chassis designs that use standard 20-series profile structures.
For custom chassis development, the available open-source models provide a starting point for both profile-based and fully enclosed chassis layouts. Designers can modify the mechanical arrangement to suit their project requirements and manufacture the resulting chassis through 3D printing or sheet-metal fabrication.
- Profile Chassis: Supports development of modular chassis structures using compatible aluminium profiles.
- Fully Enclosed Chassis: Provides a model for custom body and enclosure development.
- Custom Cut-Outs: Chassis designers can plan body openings around the suspension slot to simplify wiring routes.
- Secondary Development: Open-source models can be modified to suit custom vehicle layouts and mechanical requirements.
- Fabrication Options: Modified designs can be adapted for 3D-printed or sheet-metal chassis construction.
Applications
- Unmanned Ground Vehicles (UGVs): For compact ground robot platforms using compatible DDSM210 or DDSM400 hub motors.
- Autonomous Ground Vehicles (AGVs): For mobile robotic chassis requiring a compact spring suspension arrangement.
- Mobile Robotics Platforms: For custom robots where wheel suspension and limited chassis space are important design considerations.
- Research & Development Robots: For experimental vehicle platforms used in robotics engineering and mechanical development.
- Modular Aluminium Profile Chassis: For robot frames built using compatible 20-series European-standard aluminium profiles.
- Custom Enclosed Robot Chassis: For projects using modified open-source chassis models and custom enclosure fabrication.
- 3D-Printed Robotic Vehicles: For chassis designs adapted from the available open-source models for additive manufacturing.
- Sheet-Metal Robot Chassis: For custom fabricated vehicle bodies designed around the suspension mounting arrangement.

Installation & Operating Recommendations
Install the suspension on a mechanically suitable chassis structure using the supplied 20-series European-standard T-nuts. Correct alignment with the compatible hub motor and chassis is important for proper wheel movement and suspension operation.
- Confirm Hub Motor Compatibility: Use the assembly with compatible DDSM210 or DDSM400 hub motors and the corresponding mounting arrangement.
- Use Compatible Aluminium Profiles: Mount the suspension on a suitable 20-series European-standard aluminium extrusion profile.
- Secure the T-Nut Mounting: Position the supplied T-nuts correctly in the profile slot and tighten the mounting fasteners securely.
- Respect the Per-Wheel Load Rating: Keep the load on each suspension unit within the specified 3kg capacity. Account for uneven load distribution and dynamic forces when designing the complete vehicle.
- Plan Chassis Clearance: Allow sufficient space around the suspension for spring movement, wheel travel and mechanical assembly.
- Plan Cable Routing: Consider the suspension slot and chassis cut-outs during design so that motor wiring does not interfere with moving components.
- Check Mechanical Alignment: Ensure that the suspension, hub motor and chassis mounting points are aligned correctly before operating the vehicle.
- Inspect Spring Movement: Check for unobstructed spring travel and interference with the chassis or adjacent components during initial testing.
- Adapt Open-Source Models Carefully: Preserve mounting locations and required clearances when modifying the profile or enclosed chassis models.
